SAW-FILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 234,228, dated November 9, 18 80,

Application filed May 19, 1880.

To all whom it may concern Be it known that I, PHILIP BOSSER'I, of Lebeck, in the county of Cedar and State of Missouri, have invented a new and useful Improvement in Saw-Filing Machines, of which the following is a specification.

Figure 1 is a plan view of the improvement. Fig. 2 is a sectional side elevation taken through the line as m, Fig. 1. Fig. 3 is a sectional end elevation taken through the line y 3 Fig. 2.

The invention consists in pivoting the fileholder to a bar adapted to slide horizontally in a swinging frame that is pivoted to a carriage which slides parallel to the saw-clamp, as hereinafter described.

A represents the bed-plate or base of the machine, which is designed to be secured to a bench or other support.

To the forward edge of the plate A is attached the clamp B, between the jaws of which the saw is secured by hand-screws or other suitable means.

In the rear side of the inner jaw of the clamp B is formed a groove to receive the edge of the sliding plate 0, ora tongueformed upon the said ed ge. The other or rear edge of the plate G, or a tongue formed upon the said edge, euters a groove in a cleat, D, attached to the rear edge of the bed-plate A.

To the forward part of the plate or carriage U is attached a post, E, having an arm, F, attached to its lower part. To the upper end of the post E is attached an arm,Gr,par-allel with the arm F.

To and between the outer ends of the arms F G is pivoted a wing or swinging plate, H,

-which has an arm formed upon or attached to its upper rear corner to overlap the curved bar I, attached at its ends to the upper ends of two posts, J. The lower ends of the posts J are attached to the rear part of the carriage O.

The swinging plate H is secured in place, when adjusted, by a pin, K, which passes through a hole in the arm of the said swinging plate H and through a hole in the curved.

(Model.)

bar I. Several holes are formed in the curved bar I to receive the pin K, so that the swinging plate H can be adjusted as the kind of saw to be filed may require.

In the side of the upper part of the swinging plate H is formed a groove to receive the sliding bar L, to which, toward its rear end, is pivoted the rear upper corner of the fileholder M.

The sliding bar L and the file-holder M are kept in place by the bar N, attached to the upper part of the swinging plate H, and which is rabbeted upon its lower side to overlap the upper edge of the file-holder M.

Upon the forward end of the holder M is formed a handle, and the lower edge of the said holder is recessed to receive a file, O, and to form shoulders, to which the ends of the file 0 are secured. The shank of the file O fits into a socket in the forward shoulder of the holder M, and its point fits into a socket in the end of the screw or pin m, attached to the rear shoulder of the said holder. The upper edge of the holder M is inclined from its rear end toward its handle, so that the forward end of the said holder can be raised when drawing it back to raise the file away from the saw-teeth. With this construction the fileholder M is operated with one hand, while the carriage C is moved forward with the other hand, to carry the file from one tooth to the next as each tooth is filed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a saw-filing machine, the combination, with the sliding carriage (3, havingframe E F G, of the horizontally-swinging adjustable plate H, having a lengthwise groove, and guide-bar L, adapted to slide therein, the file-holder M, which is pivoted to said bar, and the sawclamp, all said parts being constructed and arranged to operate as shown and described.

PHILIP BOSSERT.
